Economics is divided into two sub-categories: microeconomics and macroeconomics.

Microeconomics is the study of the behaviour of small economic units. Microeconomists study the supply and demand of individual businesses and consumers, for example.

Macroeconomics is the study of broad economic activities and trends. Macroeconomists study the industrial sector, the services sector, or the farm sector, for example; however, they don't consider specific parts of any of these sectors. Factors studied include inflation, unemployment, and industrial production, often with the aim of determining the effects of government policies on these factors.
